Over/Underclock utility for 1155?

[Markstar]

Hi,
to adjust frequency and voltage, I used CrystalCPUID for my 775 systems and old AMD systems, but with the newer sockets, I use K10stat for AMD CPUs.

Now I got a 2500K and was wondering what the best tool is to switch from my overclocked multiplier/voltage to a nice energy-saving setting when idle (which would be 16x/0.8V, I guess, right?).

So, what do you guys recommend for this?

Thanks in advance!

The motherboards bios is the best tool these days.


What motherboard did you get? As long as you just up the multiplier and don't disable the c-states your chip will throttle down at idle and ramp up under load to your desired overclock.

Gigabyte Z77X-S3H (because of the 4 PWM connectors, though I was VERY disappointed to find out that only 2 are software-controllable).

No - even though the CPU is at 16*100MHz right now, the core voltage is still the 1.3V that I need for the 4.6GHz.

And iirc it should very well be possible to go all the way down to 0.8V (or even less if the CPU would allow it).

do you have Intel Speedstep or EIST disabled in the BIOS?

Use DVID to control voltage not fixed voltage I think on that board. Maybe BIOS screenshots of settings ngs if possible would help.

Nope. And to be sure I tried both settings (auto and enabled).

Hmm, DVID really isn't practical at all. It changes the VCore dynamically, but not at reasonable levels. Instead of 0.8-1.3V it goes from 1.1 to a whopping 1.595V!

Are you guys really telling me that 5 years ago, I could comfortably use a program to specify the multiplier and voltage and now I can't anymore and have to fiddle with the BIOS again? Feels like using switches on the motherboard might be next...

You should have negative value on DVID. Its a offset value for the vcore. Set to +0.005v's and see what you get. Adjust value from there. You should be able to use - value also.

Your MB maker should have a tool to alter in windows.

Hmm, I tried this and the system became unstable, so I could not really play around with it so much right now (will try again tomorrow, maybe).

Gigabyte has a program called EasyTune - really horrible, buggy and even if it works it requires a restart to apply the settings - so you might as well do them in the BIOS in the first place.

I think I'll try to install CrystalCPUID tomorrow and see what happens.

You need to adjust DVID to get it back to same core needed as before under load. Initial seeying just to see what you get. Using offset
can be tricky sometimes as can be stable under 4 core load but unstable under single core load. More often this at higher clock speeds.

Does this look similar to your uefi bios? If so try setting the vcore to normal and then using DVID + 0.060v's and see what the loaded vcore is. If it's higher or lower than the 1.30v's you need then adjust it accordingly. I'm not sure how you tried it the first time and got such high results. Maybe left the vcore on auto then used DVID?
